of Janthina globosa location and population size (Deudero S, Pinnegar J, Polunin N. 2002). Distribution and Habitat Four other species that fall in the genera Janthina can be found in the Mediterranean Sea (along with Janthina globosa) but they are also found between these latitudes: 50°N and 40°S. If conditions permit it, these snails can be found outside these latitudes. Strandings of this species and others of its genera are also due to wave and current movements (F. Betti et al 2017). Minimum recorded depth is 0 m. Maximum recorded depth is . Taxonomy Janthina globosa was first captured in 1822 off the Gulf of Antalya in the Northeastern part of the Mediterranean Sea (Teker S, Gökoğlu M , Julian D. 2017). The oldest fossil of the Janthina genera was found on Santa Maria Island in the Atlantic, but the earliest record of Janthina globosa specifically is unclear, despite its long fossil record (Record of the Australian Museum, 2017, 142). Many other species fall in the genera Janthina. J. globosa most likely evolved from the species J. krejcii, but it looks more like J. pallida (Record of the Australian Museum, 2017, 160-161). It is thought that Janthina globosa was used as a source of purple dye for clothes in ancient times. Behavior This species lives its life upside down attached to air bubbles that it made itself, forming a self-made float. These air bubbles are produced by a specialized organ called the propodium. This organ sucks air from above the surface of the water to create a bubble. It then coats it with a covering of mucus before adding it to the bottom of the float. It is further adhered to the float with more mucus to ensure it is secure. This bubble making process has been timed and it took one organism of the Janthina genera about a minute to completely form one bubble (Wilson and Wilson, 1956, 300). This mechanism of staying afloat is almost entirely unique to the Janthina genera, with the one exception being the Recluzia. Janthina globosa is not restricted to living in the open ocean; they can also live in enclosed bays if the weather conditions allow them to. Reproduction Janthina globosa is hermaphroditic and reproduces sexually. This means that it does not stay as the sex that it was at birth but begins life as a male, and then exhibits a cycle of
